Insulator     Last updated on           , a full moon day

3 kinds of insulator are Insulating layer, Insulation Oil, and SF6gas. Also see: DEE, dark energy engineering;  

Insulating layer

Inside semiconductors, layers' materials and methods may vary, depend on designer's tactical knowledge; In addition to WHICH oil and/or gas, WHICH layer in lithography dimensional distance [ after year 2008, 65nm to 45nm ] must also be concerned;

Inside NV memory, IFF layer behaves insulator, AND it scatters light, is called amorphous state aka non conductive, especially in PCM engineering; IFF layer behaves conductor WHICH reflects light, is called crystalline state aka conductive, especially in PCM engineering;

 

Insulation Oil

Among Insulation Oil(s), Mineral Oil [Inside capacitor and transformer] is the cheapest, compare to Alkyl Benzene [Cable's high resolvability], Alkyl Diphenyl Ethane [Inside capacitor], Alkyl Naphthalene [Inside capacitor], and Silicon Oil [Water resolvability in-vehicle transformer];

SF6 gas

SF6gas' dielectric strength is very high, because stable up to 1800K temperature;
